Graphical Abstract:


Background: A new wireless multiple access technology enabled by using Time Modulated Arrays (TMAs) is proposed in this paper.

Methods: It benefits due to the requirement of only a single Radio Frequency (RF) chain, compared with other multiple-RF-chain schemes.

Results: As a result, it is able to greatly reduce the system cost, energy consumption, and complexity.

Conclusion: In addition, the signal through the single RF chain is narrow-band modulated, reducing the signal Peak-to-Average-Power-Ratio (PAPR), thus, further enhancing the power efficiency of the RF chain, especially for power amplifiers. The operation principle and synthesis approach are elaborated in this paper, and are demonstrated with two examples.
